Alexandersmother, who was deaf, would have people talk to her through her ear tube, whichamplifies speech by talking through a object that looked like a horn. Alexanderchoose to talk to his mother by speaking in low tones very close to herforehead.

    Alexander thought that his mother would be able to “hear” him by thevibrations his voice put on her forehead.
